Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Acts upstream of or within in utero embryonic development; regulation of epidermal cell differentiation; and skeletal muscle cell differentiation. Predicted to be located in mitochondrion and nucleoplasm. Predicted to be active in nucleus. Is expressed in several structures, including alimentary system; branchial arch; genitourinary system; hemolymphoid system gland; and limb. Orthologous to human MAFF (MAF bZIP transcription factor F). [provided by Alliance of Genome Resources, Apr 2022]
